AQI: Good (0 - 50) AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
AQI: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects members of sensitive groups may experience more serious health effects.
 AQI:Very Unhealthy (201 - 300) AQI: Very Unhealthy (201 - 300)
Health alert: everyone may experience more serious health effects.
AQI: Hazardous(301 - 500) AQI: Hazardous (301 - 500)
Health warnings of emergency conditions. The entire population is more likely to be affected.

Forecast Discussion: Above average temperatures and humid conditions are expected over the next few days. On Friday, the above average temperatures will lead to a mixed bag of Good/Moderate AQI for ozone across the region after a weak cold front moves through then stalls across the region. On Saturday very warm air moves into the region. Temperatures are expected to climb to near 90F under sunny skies. Ozone concentrations will increase, but starting from fairly clean conditions and with weekend emissions, the region should remain in the Moderate AQI range. A wildcard for Saturday will be the potential influences of wildfire smoke from the southeastern US. Sunday will again be above normal but increasing clouds, winds, and a chance for afternoon storms should mitigate increasing ozone concentrations resulting in only Moderate AQI for ozone. -MDE
